| Abstract: | Spatio-temporal dynamics of suspended
sediment concentration (SSC) in Indian
Ocean during the 2004 Sumatra tsunami
was analyzed using satellite data. Surface
SSC in epicenter area increased
notably right after the tsunami week (about 200% higher than that in the same
period in earlier 4 years); the surface SSC in a deep water area about 1600
km from the epicenter area did not increase after the tsunami. Increase of
SSC in the epicenter area may be
mainly caused by the transportation of SSC by the tsunami backwash. Range of
spatial clustering in SSC significantly decreased during the tsunami week. It may
be related to the tsunami waves that diluted the spatial clustering level in
SSC. A new spatio-temporal correlation
model shows that the fluctuation in the
spatio-temporal correlation surface of SSC appeared remarkably intense round
the tsunami. Present study reveals that the tsunami considerably disturbed the
spatio-temporal dynamics in SSC. |
